APPARATUS FOR RECEIVING-AND HANDLING MOLTEN MATERIALS.

SPECIFICATION forming part of Letters Patent'No. 721,288, dated February24, 1903. Application tiled July 31,1902. Serial No. 117,770. (Nomodel.)

To all whom ,it may concern.-

Be it known that I, PAUL DANCKWARDT, a citizen of Germany, residing atDeadwood, Lawrence county, South Dakota, have invented certain new anduseful Improvements in Apparatus for Receiving and Handling' MoltenMaterials, of which the following is a specification.

This invention relates to an apparatus for receiving metals, matte,litharge, and other molten materials when tapped from the furnace andcasting them into ingots. By my invention the manipulation of the moltenmaterial is simplified, and the life of the apparatus is extended.

In the accompanying drawings, Figure l is a side elevation of myimproved apparatus;

. Fig. 2, a plan; Fig. 3, a section on line 3 3,

Fig. 2; Fig. 4, a section on line 4 4, Fig. 2; Fig. 5, a rear view ofthe apparatus, showing the cover; Fig.' 6, a section similar to Fig. 3,showing the cover; and Fig. 7, a perspective view of the cover.

The letter a represents a shallow iron pot cast in one piece and havinga flat bottom and inclined sides and ends, that gradually taperfrom topto bottom. The pot is mounted upon Wheels b, turning on axles b', castin studs a', Fig. 4. The axles are placed slightly in t-he rear of thepot center, so that the pot has a slight overweight at the front. Ahandle o, bolted at c', is provided with a brace c2 and a foot c3, thelatter supporting the pot in itsy normal horizontal position. The sidesa2 of the pot are extendedupwardlyT at the rear to form angularprojections c3, that extend above the upperedgeof the back a4- In thisway there is formed between the projections as and above the back a4 anopening for the discharge of the cake or ingotwhen vthe pot. is tiltedbackward, (dotted lines, Fig. l.) Upon being thus tilted the pot issupported upon the Wheels b and upon the rear edge a5 of projections a3,so as to slightly overhang backward. Owing to the sudden jar resultingfrom the tilting of the pot the solidified cake will be thrown out overthe back a4 and between the sides a2, so that the pot is rapidlyunloaded.

In order to insure a uniform expansion of the shallow pot While filledwith matte, I arrange within the pot a false bottom d and a false fronte, as these parts are most exposed to the action of the entering matte.The plates d and e are removably secured to the bottom and front bycountersunk bolts d e' and nuts d2 c2, so that they may be readilyreplaced when worn; As the entering matte first strikes against thebottom and front of the pot these parts, it unprotected, would ex pandmore than the rest of the pot, and cracking of the latter would beunavoidable. By attaching the plates d and e in the manner described thepot is allowed to freely and uniformly expand.

In order to protect the workmen from burns, I employ a cover composed oftwo straps f, having downwardly-bent ends f7 and f8. These straps areconnected by a cross-bar f5 and are riveted at]c3 and f4 to two angularbands f', having handles f6. The inclined rear sections of the bands fcarry a screen f2. The cover tits between the projections a3 of pot aand is held in position by the flanges f7 and f8,"which embrace thefront and rear sides of the pot. Y

The pot is mudded in the usual manner after each tap and will thus notallow any molten metal to runv out of the bolt-holes.

It will be seenthat by my invention the handling of the molten metal,litharge, matte, dac., is greatly simplified, that the life of theapparatusis prolonged, and that the molten material may be readilyremoved from the furnace and cast into ingots.

What I claim isl. An apparatus for handling molten materials, composedof a wheel-mounted pot having a back, and sides that are projected abovethe back, substantially as specified.

2. An apparatus for handling molten materials, composed of awheel-mounted pot having a back, and sides having rear angularprojections extending above the back and adapted to support the pot inits upright position, substantially as specied.

3. VAn apparatus for handlingmolten materials, composed of awheel-mounted pot having a fiat bottom and an inclined straight front, afalse bottom, a false front, and means for removably securing said falsebottom and false front to the pot, substantially as specilied.

4. In an apparatus for handling molten materials, a Wheel-mounted pot,combined pair of straps, a pair of angular bands conwith a cover havinga pair of straps, a pair neoted thereto, and a screen secured to said ofangular bands connected thereto, and a bands, substantially asspecified.

screen secured to said bands, substantially Signed by me at Deadwood,South Dakota,

5. An apparatus for handlino' molten materials, composed of aWheel-nouuted pot PAUL DANCKWARDT' having sides that project above thepot back, Witnesses: a removable false bottom, and a removable R. N.OGDEN,

1o false front, combined with a cover having a GEO. W. INGLIS.
